摘要

An apparatus for creating a cemented lateral junction including a sleeve (10) with a premachined opening (12) and a cover (14) disposed at the sleeve. A release material (16) is disposed at the cover. Further disclosed is a method for constructing a wellbore which includes preparing a sleeve (10) with a premachined window (12) and a cover (14) positioned to occlude the window and a release material (16) at least a portion of the cover exposed to environment through the window for running in the wellbore. The method may further include installing the sleeve in a wellbore and applying a hardenable agent to an annulus of the wellbore around the sleeve.
